About two hours before Wednesday night's game, the Warriors' adolescent-faced assistant coach, Darren Erman, stepped on the court and swished an awkward-looking two-handed jump shot.

Head coach Mark Jackson couldn't help but jokingly toss some trash at bystander Klay Thompson. "What is this? Is this that movie where the ball boy steals the star player's jumper skills?"

If so, Erman had returned those shooting skills to their rightful owner by the third quarter. That's when Thompson shot his way out of a season-long slump and propelled his team to a 102-93 victory over Brooklyn at Oracle Arena.

"That shot is a thing of beauty, and it's great to see him knocking it down," Jackson said. "I was never concerned, because I would have taken his bad shooting night for 17 years of my (playing) career. ... The guy is a key part of the future of this team. We need him, and we're a different team when he's making that shot."

Thompson led a third-quarter comeback surge and finished with 23 points while shooting better than 41.2 percent from the floor for the first time this season.

The silky shooter came into the game having connected on only 33.3 percent of his shots from the field and 30.6 from three-point range, and it had gotten even worse as of late. After scoring in double figures for 21 consecutive games, Thompson averaged 7.5 points during his past four games while shooting 23.4 and 15 percent.

"It was great to see Klay take and make shots," Jackson said. "I've said all along that I'm not concerned about Klay's shooting. That's like being concerned about Albert Pujols' hitting. It's going to turn. He works too hard, and it's a gift. You don't lose a gift."

Thompson started Wednesday's game 2-for-7 from the floor, but he made a 19-footer to open the second half, and that foreshadowed the rest of his game. On three consecutive third-quarter possessions, he hit a 17-footer and a 27-footer and then found Carl Landry for a finger roll with 2:42 remaining to give the Warriors a 65-63 lead - their first of the game.

All told, Thompson had 12 points and two assists in the third quarter. His jumper had his teammates jumping on the sideline and the crowd of 18,374 jumping out of their seats, and it helped the Warriors overcome a 13-point deficit.

The Warriors (7-5) overcame a halftime deficit for the first time this season and snapped a four-game losing skid in the series against the Nets (6-4). The game represented the first in a string of five home games out of six for the Warriors, who started the season by winning four of their first seven road games for the first time since 2007.

Stephen Curry scored a team-high 25 points and added six rebounds and four assists, but his streak of 32 consecutive free-throw makes ended in the first half. David Lee had 20 points, 13 rebounds and six assists for his seventh double-double in the past eight games.

Brooklyn got 22 points from center Brook Lopez, but no one else scored more than 13. All-Star point guard Deron Williams was limited to nine points on 4-of-12 shooting.

The Warriors missed their first five field-goal attempts and were in an eight-point hole less than five minutes into the game. During a game-opening, 14-6 run, Lopez had six points and Williams dished out three assists.

Guess who defended Williams most of the night?

Yep, Thompson was playing defense consistently even when his shot wasn't falling.
